getc() is an I/O function equivalent to fgetc() also expects a stream as parameter, but getc may be implemented as a macro. This function is used to return the next character from the input stream then increases the file position indicator. The character read by this function is a unsigned char which is converted to an integer. If the End-of-File is reached or a reading error occurs the function returns EOF.

    int getc (FILE *stream);

   #include <stdio.h>
   int main()
    {
      int c;
      int count;
      FILE *stri = fopen("getceg.txt", "r");
       while( c != EOF ) 
        {
           c = getc(stri); 
            if (c == 'A') count++;
        }
      fclose(stri);
      printf ("File contains %dA.\n", count);
      return 0;
    }

    File has the character A 3 times.

In the above example the function is used to get every character of a text file till EOF. A loop is used to find the number of times the char 'A' is found in the file. The content of the text file is "ABCA1@@ABNM".
